IMPROVEMENT IN APPARATUS FOR MANUFACTURING lLLUMlNATlNG-GAS.

Specification forming part of Letters Patent No. 217,308, dated July 8, 1879; application filed March 3, 1879.

Toall whom it may cancer M Be it known that I, WILLIAM B. WEST, of Indianapolis, in the county of Marion and State of Indiana, have invented a newand useful Apparatus for Manufacturing Illuminating-Gas from Steam and Hydrocarbon Oils, of which the following is a description, reference beinghad to the accompanying drawings.

My invention relates to a new apparatus for manufacturing illuminating-gas.

The object of my invention is to provide a system of newly constructed and arranged steam and oil pipes and nozzle, having new modes of operation for introducing steam and oil into a retort for the manufacture of illuminating-gas.

My invention consists in the new construction, arrangement, and combination of a nozzle having an outer case or T-coupling, with its branch opening below the contracted mouth of a steam-pipe, and also provided with a U- shaped oil-supply pipe, a steam-pipe, and a coil-pipe in a retort, whereby dry steam is employed as the injective power and the hydro carbon oils are drawn upward from the U- shaped oilpipe mixed with the dry steam in the form of spray, the steam becoming thoroughl y saturated with the vapor of the oil at a temperature above that of boiling water, and the mixed gases thus generated and mixed in the pipes are permanently fixed in the heated coils and retort before leaving them for the washers, the purifiers, and gas-holder.

In the accompanying drawings, in which like letters of reference in the different figures indicate like parts, Figure 1 represents a perspective view of my new apparatus for manufacturing illuminating-gas. Fig. 2 is a sec-" tional view of the steam and oil supply pipes,

other end passes through the retort and connects with the pipe F, which extends upward above the top of the retort, and also connects with one end of the T-coupling or case G. The other end of the Tcoupling or case G is provided with a pipe, R, having a contracted mouth, S. Said mouth S extends inside of the T-coupling G, and projects about half-way over the branch opening G below. The other end of the nozzle-pipe R is provided with a valve or cook, L, and then turns down, forming the drip-pipe 0, said drip-pipe 0 being also provided with a T-couplin g, W.

The steam-pipe N connects the branch W of the T-coupling W with a steam-generator, (not shown,) and is provided with a valve, N, for regulating the quantity of steam used.

The drip-pipe 0 leads to a tank below, and is designed to convey the condensed steam downward, while the live steam passes through the pipe R and contracted nozzle S into the pipe F and coil D.

The oil-tank P is located above the injector or nozzle S, and is connected to the branch opening G of the T-coupling G (which is below. the mouth of the nozzle S) by the U- shaped pipe or oil-trap H H. The pipe H is also provided with a cook or valve, J, for regulating the flow of oil.

Having thus described the construction and arrangement of pipes, valves, and retort, I will now describe the process by which the oils and steam are mixed and introduced into the heated coil and retort and converted into a permanently-fixed gas for illuminating purposes, to wit: The oil is fed by the U-shaped pipe H H to the T-coupling or case G, and discharged therein below the contracted inward-projecting mouth S of the steam-pipe R, the quantity of oil being regulated by the valve J. a The steam as it passes through the contracted end S of the pipe It forms a vacuum and draws the oil up into the case G, and also in contact with the steam, the velocity of the steam carrying the oil with it in the form of spray and heating the oil beyond the temperature of boiling water, thus forming a thorough mixture of the oil-vapor and steam, which is forced into and through the pipe F and coilpipes D, and discharged at the rear end of the retort B, thus causing the carbureted vapors to be heated to a Very high degree, andconvertin g them into a permanent fixed gas in the coil and retort, from which the gas is conveyed to the washer or scrubber and the puritiers, and finally into the gas-holder, thus producing a very rich and highly-illuminating gas from oil and steam.

I am aware that retorts containing coils of pipes, also U-shaped pipes or traps, are old, and that variously-constructed nozzles are now in use; but I am not aware that a nozzle constructed and arranged to operate inconnection with steam and oil supply pipes "and a coil of pipes in a retort have been constructed and arranged to operate in the manner setforth in my application.

What I claim as new, and desire to secure WILLIAM B. WEST.
